  • 4/0 (LX) is not the same as 4/0.
Size: 4/0 Awg (Xl) - 5/16" (M8) Ring Number of Items: 10
Very good quality. Just be aware of the description . I needed 4/0, but I bought 4/0 (XL) by mis-reading the description. Be ⚠️ cautious.

  • Works!!
Size: 1/0 Awg - 3/8" (M10) Ring Number of Items: 10
Used for solar battery connections and is working great so far. Lug weight, feel and appearance seem to be of good quality. Very good fit for cable and stud sizes. Product came promptly and well packaged.

  • Buy them, don't hesitate
Size: 8 Awg - 5/16" (M8) Ring (Wide Pad) Number of Items: 25
These are easily as good as anything you'll buy in a hardware store. The SELTERM brand have been the best I've found on Amazon. I've bought everything from 10GA to 2GA, all with 5/16 or #10 hole. They compress well and firmly around your wires. I've used them with a hydraulic crimper and a hammer crimper. They just perform admirably. ... show more

  • Exact fit for 2/0 welding cable
Size: 2/0 Awg - 3/8" (M10) Ring Number of Items: 10
I was worried the inner diameter would be too small for the 2/0 welding cable. Plenty of room putting the stripped cable into copper. I pack my fittings with grease, then put the cable in. The grease prevents corrosion inside the lug. I live in the northeast.........salt on roads, corrosion, etc. Former chief engineer on an ocean going tug......saltwater=corrosion. Add in heat and electricity and oxygen in the air and you have corrosion. The grease displaces the air within the fittings and strands of copper. Also helps to prevent moisture/water migration between the strands and outer rubber insulator. I used a hydraulic crimper that I purchased on Amazon years ago......nice tight fit. Then I put shrink tube over the finished crimp. All in all..........nice lugs, cheap money..........certainly less expensive than the welding store!! ... show more
